Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 20,094,347, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 20,094,347 | |
| -1 | -20,094,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,094,347.
Example:
1 x 20,094,347 = 20,094,347
and
-1 x -20,094,347 = 20,094,347
Notice both answers equal 20,094,347
With that explanation out of the way, let's continue. Next, we take the number 20,094,347 and divide it by 2:
20,094,347 ÷ 2 = 10,047,173.5
If the quotient is a whole number, then 2 and 10,047,173.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 20,094,347 | |
| -1 | -20,094,347 |
Now, we try dividing 20,094,347 by 3:
20,094,347 ÷ 3 = 6,698,115.6667
If the quotient is a whole number, then 3 and 6,698,115.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 20,094,347 | |
| -1 | -20,094,347 |
Let's try dividing by 4:
20,094,347 ÷ 4 = 5,023,586.75
If the quotient is a whole number, then 4 and 5,023,586.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 20,094,347 | |
| -1 | 20,094,347 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 439 | 503 | 3,073 | 3,521 | 5,707 | 6,539 | 39,949 | 45,773 | 220,817 | 1,545,719 | 2,870,621 | 20,094,347 |
| -1 | -7 | -13 | -91 | -439 | -503 | -3,073 | -3,521 | -5,707 | -6,539 | -39,949 | -45,773 | -220,817 | -1,545,719 | -2,870,621 | -20,094,347 |
